Is Red & Green Really Lean? Color Coding & Bowling Charts vs. Process Behavior Charts
Practice session for a talk given April 26, 2021 by Mark Graban at the Central Coast Lean Virtual Summit 2021: BUILD BACK LEANER
In the context of metrics for Lean management, are we continuing to improve and evolve? Are we stuck in the “way I was taught” or “the way we’ve always done it”? If so, should we aspire to do better? We can.
Many organizations use a method for displaying metrics that’s often called “bowling charts.” Can we really see statistically meaningful “trends” in a long list of numbers? If we color code each number as red or green, some say we can tell if we’re “winning or losing” – but are we improving? Are we really improving?
In this talk, Mark Graban introduces a method, “Process Behavior Charts,” that is almost 100 years old. It’s not outdated, it’s proven. Process Behavior Charts help us distinguish between “signal” and “noise” in our metrics. They help us better evaluate our attempted improvements. They help us react less, lead better, and improve more.
